In truth the LubeGard PSF shown doesn't state that it 'meets' any spec. Like most multivehicle products, it uses "suitable for" to describe it's use. Doesn't mean not a good/quality PSF, in fact being a synthetic PSF and Lubegard, likely a quality product. Not sure about the cost though.

Doing just a little googling it seems PSFIII equivalent to Dexron II/III ATF. 'If' true an easy spec to meet with ATF, including the Multivehicle Synthetic ATFs like MaxLife. My advice, google Kia PSF III equivalents, and go to some of the Hyun/Kia vehicle specific forums and see what the folks are using. Most I see using a Dex III 'or better' ATF equivalent, some MultiVehicle ATF products. And the LubeGard 'suitable for' listings would 'seem' to confirm information.

Thank you. I did some searching and found this to be the case. Not 100% sure I feel confident about using ATF in a PS system, but I guess that's what the KIA fluid "was" at some point. Not much on the KIA forums regarding this question. Most have advised as you have.

Yeah, I get it. As comparison I have an 01 Tacoma and it calls for DexII/III ATF, but they don't use any coded name for the product like PSF-3, just straight out says the ATF spec. As noted, lots of good reasonably priced ATFs easily meet the Dex II/III spec.

I've used Maxlife Atf in my '03 Hyundai Santa Fe. Runs great with no noise. The one think that I will add is that I feel that it is thinner as it caused the power steering hoses to leak and the rack to leak. But I don't think that was the fluids fault as my car has a history of leaking hoses and the rack boots were torn up for a while when I got it.

And one anecdote on this thread supporting the ATF conclusion.

- Good to know! Thanks for your help!

Power steering systems are nothing more than a simple hydraulic system. Nothing Special. You could use any ISO 32 or 46 hydraulic fluid in that system without a problem. A pump, a reservoir, hoses and a cylinder. Sometimes a cooler.

I recall my 2008 Hyundai Santa Fe calling for Hyundai/Kia PSF-4 which was impossible to find aftermarket. I think it was the one fluid I didn't swap out on that vehicle. Hope the current owner appreciates it whomever that may be!
